Order this document by MC3458/D Utilizing the circuit designs perfected for the quad operational amplifiers, these dual operational amplifiers feature: 1) low power drain, 2) a common mode input voltage range extending to ground/VEE, and 3) Single Supply or Split Supply operation. These amplifiers have several distinct advantages over standard operational amplifier types in single supply applications. They can operate at supply voltages as low as 3.0 V or as high as 36 V with quiescent currents about one–fifth of those associated with the MC1741C (on a per amplifier basis). The common mode input range includes the negative supply, thereby eliminating the necessity for external biasing components in many applications. The output voltage range also includes the negative power supply voltage. • Short Circuit Protected Outputs • • • • • • • • DUAL DIFFERENTIAL INPUT OPERATIONAL AMPLIFIERS SEMICONDUCTOR TECHNICAL DATA 8 True Differential Input Stage 1 Single Supply Operation: 3.0 V to 36 V P1 SUFFIX PLASTIC PACKAGE CASE 626 Low Input Bias Currents Internally Compensated Common Mode Range Extends to Negative Supply Class AB Output Stage for Minimum Crossover Distortion Single and Split Supply Operations Available 8 1 Similar Performance to the Popular MC1458 D SUFFIX PLASTIC PACKAGE CASE 751 (SO–8) PIN CONNECTIONS MAXIMUM RATINGS Rating Power Supply Voltages Single Supply Split Supplies Symbol Value Vdc VCC VCC, VEE 36 ±18 Input Differential Voltage Range (1) VIDR ±30 Vdc Input Common Mode Voltage Range (2) VICR ±15 Vdc TJ 150 °C Tstg –55 to +125 °C Junction Temperature Storage Temperature Range Operating Ambient Temperature Range MC3458 MC3358 Output A Unit 2 7 3 0 to +70 –40 to +85 NOTES: 1.

The first stage of each consists of differential input devices Q24 and Q22 with input buffer transistors Q25 and Q21 and the 4 differential to single ended converter Q3 and Q4. The first stage performs not only the first stage gain function but also performs the level shifting and transconductance reduction functions. By reducing the transconductance, a smaller compensation capacitor (only 5.0 pF) can be employed, thus saving chip area. The transconductance reduction is accomplished by splitting the collectors of Q24 and Q22. Another feature of this input stage is that the input Common Mode range can include the negative supply or ground, in single supply operation, without saturating either the input devices or the differential to single–ended converter. The second stage consists of a standard current source load amplifier stage. The output stage is unique because it allows the output to swing to ground in single supply operation and yet does not exhibit any crossover distortion in split supply operation. This is possible because Class AB operation is utilized. Each amplifier is biased from an internal voltage regulator which has a low temperature coefficient thus giving each amplifier good temperature characteristics as well as excellent power supply rejection.
